Problem in MAX 2009 with vray light that doesn't appair in vewport!!

[orei]

Hi my friends.. i'm a noob of 3dstudio max 2009 with vray.. i've a problem.. with my radeon mobile 9000 video card, in the direct x coniguration, if the default light are deactivated.. and i use vray light, i can't see any light preview in viewport.. but the light appair correctly if render the scene.

 

If i use vray sun instead of vray light.. i can see the light in the viewport!!

 

I tried to use different catalyst driver.. but nothing happened..

 

If i use Opengl configuration.. everithing is ok.. but the work is too slow..

 

How can solve this??

 

Thanks a lot
